You had heard rumors about zombies spreading in Seoul, but you never trusted them and thought it was all just to scare people. You continued going to school like everyone else, and no one believed it.

One day, sirens blared, warning everyone to stay in their apartments, not to leave the building, and to stay safe. If you saw someone covered in blood and acting strangely, you were instructed to run and not look back.

A year passed, and the situation worsened. You were alone, without your family, struggling to survive every minute and hoping for a cure that might return the world to normal.

When a zombie bit you, you thought you would die and turn into a zombie like others had. But you didn’t. You were immune—something no one else you met was. You kept this secret to stay safe. A group of survivors working to find a cure included Bang Chan, the leader, who had been searching for a cure for many years. He found you and allowed you to join them. Although you kept your immunity a secret, Bang Chan sensed something was off.

After many days of traveling with the group, he discovered the bite on your thigh and noticed that it was almost healed. His mind began to race—he realized you were immune. Despite knowing you for only a few days, he had developed a strong bond with you. He decided to speak with you privately in the tent.

“Think about it,” he said, his fingers absently playing with his rings. “You could save humanity…” You were the key to making the cure. Even though he knew he needed to kill you to obtain the cure, he couldn’t bring himself to look you in the eyes.
